Hi! Im just finishing my first year and I had to make the discussion as to whether commute or live in because I live so close to my Uni.
I chose to live in. And so glad i did. The people I live with are the greatest people I've ever met and you bond with them having to live with them and because you aren't all doing the same course there are a mix of characters.
Don't get me wrong, your course mates will be your friends too, but when they are going out to freshers events or going out for tea in the evening, you'll soon feel left out.
